Signal transmission system
View Patent ↗A liquid crystal display of compact size is disclosed. The liquid crystal display has a tape carrier package and a single integrated PCB for processing a gate driving signal and data driving signal. The tape carrier package includes a base substrate, a gate driver IC formed on said base substrate, an input pattern formed on said base substrate that applies gate driving signals input from an external device to the gate driver IC, a first output pattern formed on said base substrate that outputs a first gate driving signal processed in said gate driver IC, and a second output pattern formed on said base substrate, that outputs a second gate driving signal bypassing the gate driver IC among the gate driving signals.
